But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia. Dan 10.13
Gabriel was withstood by Prince of Persia who is none other than Satan himself. Many times we find Bible using name of human kings to refer Satan. Isa 14 and Eze 28 are other examples.
While satan was resisting Gabriel for 21 days another angel Michael comes to his aid. Satan who could resist Gabriel is not able to withstand Michael.
Who is this Michael?
Michael, first of the chief heads, Dan 10.13 (Youngs Literal translation)
Michael is the head of archangels.
Also Michael is called the prince of Daniel and his people Dan 10. 21.
It is interesting to note that Michael is not only the head of Angels but also the prince of God’s children. This gives us a clue that Michael is not a normal angel like Gabriel or Lucifer. He is much more than an Angel because He is the Prince of all God’s children. Who could be a prince of people. Only King’s son is considered as the prince. To Samuel God said that He is the king of Israel. So Michael should be the son of God – Jesus Christ. Wow. Can we prove that from Bible?
John 5. 25Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live.  Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,  And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
Jesus tells us that in the last day the dead will be resurrected hearing his voice. The book of Daniel associates the resurrection of dead with Michael the archangel.
Dan 1: 1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people:………  And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
Apostle Paul also writes that Jesus will descend with the voice of Archangel.
1 Thes 4.16 For the Lord himself shall descend from heaven with a shout, with the voice of ‘the archangel’, and with the trump of God: and the dead in Christ shall rise first: (emphasis supplied by me)
Jesus is Michael the archangel.
So does Bible say that Jesus is an angelic being not son of God. Certainly not.
The hebrew word for angel simply means messenger. Even in tamil bible angel is translated as Messenger.
Jesus is the chief messenger for the Godhead. He also heads the angelic force and he is the prince of God’s people.
The Hebrew word malak (found 103 times in the OT) simply means “messenger”,” and hence employed
to denote any agent God sends forth to execute his purposes. It is used of an ordinary messenger
(Job 1:14: 1 Sam. 11:3; Luk 7:24; 9:52), of prophets (Isa 42:19; Hag 1:13), of priests (Mal 2:7), and
ministers of the New Testament (Rev 1:20).
The meaning of hebrew word Michael means the one who is like God. Bible tells us that Jesus shares the same glory as God.
Conclusion: Michael the archangel is not a created being but the creator God Jesus Himself.
